The answer would be BLITZKRIEG assuming you are doing WORLD WAR II.
Blitzkrieg or “lightning warfare” is a tactic used to overwhelm an enemy by the use of Tanks, Infantry, and Planes to ultimately surround and crush an enemy fast enough before they could respond and or figure out a plan. This method was highly effective against France, Poland, Other countries and Russia to a certain degree. Radio frequency was vital to the coordination of these attacks inorder to maintain a quick, proper attack used by all 3 factions of the army. (Plane, Tank, Infantry)
